Rail Nylon Insulator

Rail nylon insulators are installed between steel rail and tie plate, for adjusting rail gauge and electrically insulating railroad rails, clips and bolts from the interior of concrete sleepers. Rail nylon insulator has the same function as a rail pad, but it is thicker than rail pad. For the high speed or high load train, it is a necessary fastener part.

Material properties of rail nylon insulator

The insulators apply to rails such as 60kg (UIC) rail, 52kg rail, 136RE Rail, 90R, 75R, 50R, 60R etc. Its material: Nylon-6 or Nylon-66 with glass filler content 20% to 35% depending on specification. These materials are UV stabilized and available in natural color or as per requirement.
